Suppose there is a claim that a certain population has a mean, µ, that isdifferent than 9. You want to test this claim. To do so, you collect a largerandom sample from the population and perform a hypothesis test at the0.05 level of significance. To start this test, you write the null hypothesis, Hand the alternative hypothesis, H, as follows.Ho: µ=9H1: µ#9Suppose you also know the following information.The value of the test statistic based on the sample is 1.745 (roundedto 3 decimal places).The p-value is 0.081 (rounded to 3 decimal places).(a) Complete the steps below for this hypothesis test.Normal DistributionStep 1: Select one-tailed or two-tailed.O One-tailedO Two-tailed03+Step 2: Enter the test statistic.(Round to 3 decimal places.)Step 3: Shade the area represented bythe p-value.0.1-Step 4: Enter the p-value.(Round to 3 decimal places.)(b) Based on your answer to part (a), which statement below is true?O Since the p-value is less than (or equal to) the level ofsignificance, the null hypothesis is rejected.Since the p-value is less than (or equal to) the level ofsignificance, the null hypothesis is not rejected.O Since the p-value is greater than the level ofsignificance, the null hypothesis is rejected.O Since the p-value is greater than the level ofsignificance, the null hypothesis is not rejected.

Given: H0: mu =9 H1: mu is not equal to 9 Level of significance = 0.05

(b) Based on your answer to part (a), which statement below is true? Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. Since the p-value is greater than the level of significance, the null hypothesis is rejected. OSince the p-value is greater than the level of significance, the null hypothesis is not rejected.

(b) Based on your answer to part (a), which statement below is true? Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. Since the p-value is greater than the level of significance, the null hypothesis is rejected. OSince the p-value is greater than the level of significance, the null hypothesis is not rejected.

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a= 0.01, (b) a = 0.05, and (c) a = 0.10 P=0.0067 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA. Fail to reject Ho because the P-value, 0.0067, is greater than a = 0.01. OB. Reject Ho because the P-value, 0.0067, is greater than a = 0.01. OC. Fail to reject Ho because the P-value, 0.0067, is less than a = 0.01. OD. Reject Ho because the P-value, 0.0067, is less than a = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance? OA. Fail to reject Ho because the P-value, 0.0067, is greater than a = 0.05. OB.

Suppose you have a hypothesis test which never rejects the null hypothesis, no matter the value of the test statistic. Name a potential problem with such a test. Select one: O a. Using this test would lead to making an excessive number of Type Il errors. O b. There can be no problem with such a hypothesis test, this is the ideal scenario. O c. Using this test would lead to making an excessive number of Type l errors.
